Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

By figure 1 to 4 and give, including bottom plate 1, be equipped with a plurality of along left right direction equipartition and upper and lower direction's sleeve 2 on the bottom plate 1, be equipped with gliding square plate 3 from top to bottom in the sleeve 2, sliding connection has cross slider 4 on the sleeve 2, cross slider 4 upper end runs through sleeve 2 and goes up the lateral wall and be equipped with according to

piece

5, 1 front end left side of bottom plate is equipped with limit structure, 1 front end right side of bottom plate is equipped with the lantern ring 6 of upper and lower direction, sliding connection has the montant 7 of upper and lower direction on limit structure and the lantern ring 6 respectively, two montant 7 upper ends are equipped with the backup pad 8 of a left and right directions, the upper surface of backup pad 8.

In order to enable the square plate 3 to slide up and down in the sleeve 2, a circular groove 9 is coaxially formed in the sleeve 2, a rotating wheel 10 is connected in the circular groove 9 in a rotating mode, an arc-shaped groove 11 is formed in the front end of the sleeve 2, the front end of the rotating wheel 10 is located in the arc-shaped groove 11, a screw rod 12 is arranged at the lower end of the square plate 3, and the screw rod 12 is in threaded connection with the rotating wheel 10.

The limiting structure comprises a fixing plate 13 which is located on the left side of the bottom plate 1 and is in an inverted L shape, the left end of the fixing plate 13 is hinged with an L-shaped plate 14 which can be matched with the fixing plate, a hook 15 is arranged on the front side wall of the L-shaped plate 14, the front end of the bottom plate 1 is hinged with a handle 16, and a retaining ring 17 which can be matched with the hook 15 is hinged on the handle 16.

For better use effect, the outer edge surface of the vertical rod 7 is provided with a spongy cushion 18, and the upper end surface of the supporting plate 8 is provided with a soft cushion 19.

In order to reset the crosshead 4, the lower end of the crosshead 4 is connected to the square plate 3 via a spring 20.

In order to ensure that a beginner presses keys in place when in use, the crosshead shoe 4 is provided with a plurality of stop blocks 21 positioned below the press block 5.

In order to fix the device on a desk, an L-shaped positioning plate 22 is arranged at the lower end of the bottom plate 1, and a bolt knob 23 is connected to the lower side of the positioning plate 22 in a threaded mode.

When the utility model is used, the bottom plate 1 is firstly placed on a desktop, the desktop is positioned between the bottom plate 1 and the positioning plate 22, and the bolt knob 23 is rotated clockwise to fix the bottom plate 1 and the desktop;

the left vertical rod 7 is held by the left hand, the handle 16 is pulled forwards by the right hand, the handle 16 swings forwards to drive the buckle 17 to be separated from the hook 15, the L-shaped plate 14 is not tightly attached to the fixed plate 13 any more, at the moment, the vertical rod 7 can drive the supporting plate 8 to move up and down, the supporting plate 8 is adjusted to be at a proper height, the buckle 17 is sleeved on the hook 15, the handle 16 is pulled backwards, the handle 16 swings backwards to drive the buckle 17 to be tightly attached to the hook 15, the L-shaped plate 14 is tightly attached to the fixed plate 13, at the moment, the vertical rod 7 cannot drive the supporting plate 8 to move up and down due to the action of friction force, the supporting plate 8 is fixed, when the piano finger strength training is carried out, the wrist of a beginner is lifted, the wrist collapse, the finger collapse and the finger pushing of the piano beg;
